Risk factors for getting Ebola:

• Travel or work in areas with the Ebola virus
• Animal research or handling remains of primates infected from Ebola
• Providing care for people with the Ebola virus
• Preparing people who have died from the Ebola virus

Overview
Ebola hemorrhagic fever (Ebola fever) is a viral disease that has been limited to parts of Africa. It has been made newsworthy worldwide because of its destructive potential.
The exact mode of transmission is not understood. The incubation period appears to be up to 1 week, at which time the patient develops fatigue, malaise, headache, backache, nausea-and-vomiting, and diarrhea.
Within a week, a raised (papular) rash appears over the entire. The rash is often hemorrhagic(contains blood). Hemorrhaging generally occurs from the GI tract, causing the patient to bleed from both the mouth and rectum. Mortality is high, reaching 90%. Patients usually die from shock rather than blood loss.
